Okay, here's the situation. My puppy is having 100% liquid Diarrhea. This has been going on most of today. Toward the evening he began to act lethargic, but is not throwing up at all. He has eaten several times today, but seems slightly less interested in treats than he did earlier in the day.

He has had 2 parvo shots (most recent last week) so i'm desperately hoping it's not that.

Last night he got into the trash and got some cuttings from the steak i made... these were pretty much 100% fat. This is the only thing he's had that might have caused the problem as far as I know.
